I think we must draw out Buxter and perhaps Tweeker a bit more here. In general my favorite 41 is not with the older full orchestra versions: Walter, Bohm, Klemper, Karajan etc. I prefer the new smaller group recordings such as Saraste/Virgin, Glover/ASV, Menuhin/Virgin etc which almost always allow more clarity and intimacy to emerge, and also are energetic and agile in the outer movements.
The full orchestra effect is good with Beethoven and later romantic composers which utilize it's massive scale and sweeping melodies better. I usually find Haydn and Mozart more clearly expressed with small group recordings.
I find the Bernstein/DG makes best case for full orchestra 41 with very passionate/eneregetic outer movements, but I still prefer the transparency offered by smaller group recording.
